Application led February 12, 1915. Serial No. 73727.

To (/Z yri/10m 'it may concern lle it known that I, JoIIN Nnwmann Huysmans, a. citizen of the United States, residingat Greenwich, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improve-- ments in Sending Devices, of which the following is a full, clear, concise, and exact (,lescription.

This invention relates to sending devices and is jmrticularly designed for use at a telephone substation in conjunction with a register sender device at the'central station, although its use is not limited to systems employing central station register senders.

The. object of this invention resides in the provision of means whereby the desired number of impulses may be transmitted with accuracr and with great rapidity.

ln the structure disclosed in this application, each time. one of the operating members is actuated, the sender goes through a certain cycle of operations whereby it tends Y to transmit a certain definite number of im pulses. but the number of impulses which are effective, that is, the number which pass over the line circuit, is governed by the operating member actuated which interrupts the sender circuit to certain of the sending contacts.

Referring to the drawings- Figure l is a top or plan view of the device with the cover partly removed; Fig. 2 is a view substantially on the line 2-2 of Fig. 1; Fig. 3 is a diagrammatic view illustrating the sending contacts and the brush or wiper; Fig. 4 is a section substantially on the line 4-4 of Fig. 2; and Fig. 5 is a view similar to Fig. 4 shouf'inflr the': operating mechanism in a slightly different position.

Briefly described, the device herein disclosed operatesas follows: Whenever one of the keys 1 is depressed the spring 2 is tensioned to drive, by means of a suitable train of gears, the shaft 3 through a complete revolution. Carried at the upper end-of the shaft 3 is the interruptor brush 4, one end of which trails. on the continuous plate 5 1 casing through thereto to break connection with the next succeeding spring 7 (see Fig. 3). Thus, while the brush 4 in going through a cycle of operations traverses all the contacts (i, only so many of the contacts willbe effective to transmit impulses over the line asr precede the point at which an interruption occurs in the series circuit through the several springs 7 Now describing the device in detail, the finger-pieces 1 are carried by arms 8 'projecting from tle pivot members 9. The bearings for the pivot members 9 are notches in the upper edges of the casing 10 and in brackets 1l secured thereto, the top of the bearings being provided by the cover or cap plate 12 which is secured to the casing 10 by means of lugs 13 and screws therethrough, asshown in Fig. 2.

Secured in any desired. manner to the pivot member 9 of each key or actuating member, is an arm or bracket 36 to which is insulatively secured a spring 7. vWhen the sender is in its normal condition, the springs 7 occupy relative positions such that each, withtlie exception of those at each end, are engaged by the preceding spring and in turn engage the one following. -This arrangement will be readily understood from an inspection of Fig. 3." Projecting from each spring 7 is a contact 6 arranged substantially in alinement with the lpivot 9, so that when said pivot is rotated, the contact 6, carried thereby, is not displaced, but as before described, when the pivot 9 is rotated by the depression of an actuating member 1, the spring 7 carried thereby is tilted so that it breaks connection withv the following spring 7. Itfdoes' not, however, break connection with the preceding spring due to the iexibility of said springland the fact that the leftend (Fig. 3) of the actuated member 7 is shorter therefore moves a less distance.

Each ofthe pivot members 9 is provided at its inner end with a laterally and downwardly'projecting portion 14. The spring 15 secured at one end to the arm 14 and at its other end to a lug 16, carried by the casing 10, serves to normally maintain the key in its uppermost position. Secured to the l0, about midway,of the height thereof and projecting parallel to the bottom of said casing, is -a supporting member 17 which extends the shaft 3, the other formed by than the right end and endlo the shaft being journaled in the bottoni plate of the casing l0. liotatably mounted on the shaft 3 is a spider 18 having projectingfingers 19, one for each key. `Now, when one of the keys lV are depressed, the downwardliv projecting member '14. engages its respective linger, 19 and .causes the spider 1S to be rot-ated ay Jfraction of a revolution. Also rotatably mounted on the shaft 3, adjacent to the spider 18. is z ratchet wheel QG engaged by the pawl 2l pivotally secured to the lower side ofthe spider 18. Mounted on a. sleeve or collar about the shaft 3 is a spring;` 2, one end of which is fixed to the ratchet wheel 20,y the other end being secured to the gear 22. rl`hel gea r loose' on shaft 3, meshes with the pinion 23,1436. l mounted ori-the ivot screw 2li which proyec-ts from the bottom oi the casing l0. integral with the pinion 23 is a gear 25, which inturn meshes with the'pinion Q6 fixed tothe sha-ft 3. rlhus, when the spider 18 is rotated, it causes, through pawl .a clockwise direction.

2l, the rotation oi? the ratchet Q0 and this in turn tensions the spring; f2 o'li the motor. rllhe spring 2 causes the gear 22 to rotate, which vrotation is transmitted through pinion rear 25 and pinion 2G to the shaft 3 to cause the sender brush or wiper 4 to make one coinplete revolution.

Fixed to thc shaft 3, adjacent the bottom oifcasing 10, is a plate 27 having a projec-l tion 2S which is normally engaged by the hook-,like member 29,(li`ig. li) pivotally mounted on the pin 30. Fixed tothe member 29, by means of thel collar 31, is anl actuating member 32, the purpose of which will' presently appear. Coiled about the collar 3l is a spring 33, one end to the stud 3st projecting from. the bottom ci the casiifigi,f 10, the other end being; secured to the member 29." rlhis spring. tends to rotate the member 29 in an anti-clockwise direction. iVhen lthe sender is in its normal position, the l'hook of member 2*.) is in engagement 'with the radially extending surface of. the

projection 28. liivhen, however, one of, the keys ifs actuated and the spider 13 is rotated, the linger 19 the niembcr S2 to rotate it, together with the hook S25), in rllliis releases the plate-2i" which, it is remembered is secured ts normal position, mein;d e;

hook 2) ismovcd outward., the right angularlyetending portion 35, integral therewith, is Jiiorced inward and rides on the pe;

v riphery of the I plate 2T until it is engaged by v.the radially extending surface of theprojectionf, which stops the movement ot' the` happens duringthc brief 'thekey is depressed. Upon .L l L ld .i

member is actuated. Upon the return or clockwise rotation of the spider 1S the pawl 21 carried thereby rides over the teeth of the ratchet 20, the rotation of the ratchet wheel 2O being' prevented by means ot" the pawl Si',

pivotally mounted onthe collar 3l. and norp mally held in engagement with the ratchet Wheel by means of the spring 38, one end ot which is xed to .a projecting portion of the pawl 37, the other 'end being'secured to a lug 39 carried by the casing 10. During the above described operation, the shaft 3 has made a complete revolution andthe brush Je. has made engagement with each ofthe sending or impulse contacts (i. This movement of the brush 4 has taken place while the actuating member is still depressed. rl`herefore, oie of the springs will be in a position similar to that occupied by the fourth spring in Fig. 3, and if this corresponds to the key operated only four impulses will be transmitted over ythe line.

As it is obvious that nianymodifications may be made in this invention without departing! from the spirit thereof, the invention should be limited only by the scope ci' the clain'is. L

'ln a controllingn apparatus, a line, an impulse device associated therewith, devices for actuating' said impulse device, means actuated upon the operation of anyone of said actuating devices ior -ausing said impulse device to make a certain de iiiiite number of electrical contacts, andhincans governed by the operated actuatingV device fior determining' the number of said electrical contacts which will be effective to alter the electrical condition of said line.
